Can orchids be grown with pine bark? A detailed guide to the planting method

When you have grown orchids for a long time and have many of them, you will try all kinds of potting media. In fact, pine bark is also a very good potting medium for growing orchids. It is relatively economical and practical, and it has certain benefits for orchid roots, because pine trees contain abundant pine resin, from which pine oil can be scraped and rosin and turpentine can be refined. Moreover, pine bark is very difficult to rot, and it is relatively resistant to water and moisture and to decay.

Because of its characteristic of being relatively difficult to rot, using pine bark to grow orchids is also very good. After watering in the potting soil, it ferments very slowly, so the heat released is very slight. When growing orchids, root rot is not likely to occur, and the orchid roots will not be scalded by a large amount of heat. If pine bark is used in an orchid soil mix, its very slow fermentation in the potting soil can also provide the orchid roots with organic phosphorus and most other organic nutrients. Its main role is to create air pockets in the medium and increase the looseness and water permeability of the medium in the potting soil.

Now it is also used on a large scale in greenhouses. We ourselves can also collect some to use for growing orchids, and pine trees should be very easy to find near us. We can go to a place where there are pine trees and scrape off the cracked, dry, hard old bark of the pine trees, without damaging their tender bark layer. Collecting this old bark has no effect on the pine trees and will not affect their growth. The pine bark we collect must be cut into small pieces before use, about 6 mm to 8 mm is fine, as long as it is a bit smaller than our little fingernail. Before use, it must be boiled in boiling water for an hour, which can kill insects, sterilize, and also degrease it, and then it should be soaked in clean water.

Soaking in clean water takes about three days, changing the water once a day. After three consecutive days, we can take it out and dry it in the sun for later use. This kind of old pine bark can be used directly. When mixing the soil, a little nutrient-rich material can be added appropriately. For example, we can add some rotted leaves, or add some granules of peat soil. These two mixed together are very easy to use, both loose and breathable and containing nutrients, and roots grow very well in it. Of course, if you think using pine bark directly is not good and you are afraid it will burn the orchid roots, we can put it into a sealed container, add water, and ferment it, which is also fine.

For growing orchids, barks and the like are the best. One is willow bark, and another is pine bark. The bark of other tree species can also be used directly, but compared with pine bark, before use it must be thoroughly fermented. For other types of tree species, if they rot very easily, then when you grow orchids, they will ferment in the orchid potting soil and release a large amount of heat, causing the orchid roots to be damaged by heat and leading to root rot and hollow roots.

Using bark as a potting medium for growing orchids is very good. It can increase breathability and water permeability, create air pockets in the medium, and also provide nutrients to the orchid roots, so that the orchids we grow thrive, bloom when it is time to bloom, and grow when it is time to grow, and are not prone to root rot or to rotten leaves, black spots, and the like.
